✦ Synopsis
A concrete simulation model which deals with the hydrolytic polymerization of c-caprolactam (CL) in the tubular reactor (TR) with the heat exchangers (HEx's) was described, and a method for its numerical solution was presented. The numerical calculations were carried out for 13 cases, where the position and number of the HEx's in the T R were varied. The effects of the HEX on the distribution of the temperature in the T R and of the characteristic data of the polymerization (the concentration of CL and number average degree of polymerization) in the T R and a t the outlet of the T R were investigated. The results suggested that the HEX positioned a t the upper half of the T R and the HEX positioned a t the lower half of the T R are effective to narrow the temperature distribution in the T R and to produce the polymer product with narrower molecular weight distribution, respectively.
